Lichen is a type of plant that is usually found in the Tundra. It also is a type of fungi. A lichen is a symbiosis of a fungus and a photosynthetic organism, either a type of bacteria or a plant. The fungus provides protection for the photosynthetic joint of its being, and the bacteria provides energy for the fungus.
In many cases the fungus and the alga which together make the lichen may each be found living in nature without its partner, but many other lichens include a fungus which cannot survive on its own -- it has become dependent on its algal partner for survival.
